There are cases to generate a noise because VCSEL driving current flows AVDDVCSEL terminal, and to distort a waveform
of VCSEL driving current.
To reduce these influences, please arrange CX1 within 5mm from AVDDVCSEL terminal, and wire between
AVDDVCSEL terminal, CX1 and GND terminal as close as possible. Also, the wiring of AVDDVCSEL is separated from
VDD and V
terminals, and the power source of V
I2C
And in order to reduce the influence of the power supply noise, please arrange CX2 within 5mm from AVDD terminal.
Please evaluate with the actual electrical implementation, and carefully make sure that there is no problem.
SDA terminal is NMOS open-drain output and digital input. XSHUT and SCL terminals are digital input. GPIO1
terminal is NMOS open-drain output.
